论证
阳施阴化，胎孕乃成。血气虚损，不能养胎，则胎自堕。譬如枝枯则果落，藤萎则花坠。又或劳怒动火，
亦能堕胎。正如风撼其树，人折其枝也。（《沈氏尊生书》）
胎堕太多，气血耗甚，胎无滋养，故频堕也。譬之水涸而禾枯，土削而木倒。（汪石山）
妊娠少腹胀坠，须防小产之患，见红即难安矣。枝枯则果落，急宜补肾；架朽则钟堕，急宜补脾。（《见闻录》）
驴马有孕，牡者近身则蹄之，名为护胎，所以绝无小产。人之胎系胞中，气血养之，静则神藏。若欲火
一动，则精神走泄，火扰其中，则胎堕矣。可不慎哉！（《产宝百问》）
凡保胎，当养脾胃。脾胃为仓廪之官，脏腑之所禀受，胚胎由之以滋养也。胃属阳明，阳明者，冲任之长
也。（《薛氏医案》）
凡妊娠之数见堕胎者，必以气血亏损而然。而亏损之由，有禀质素弱者，有年力衰残者，有忧怒劳苦而困
其精力者，有色欲不慎而损其生气者。此外如跌扑、饮食之类，皆能伤其气血。气血有伤，而胎可无恙者，非
先天之完固者不能，而常人则未之有也。且胎怀十月，经养各有所主，所以屡见小产堕胎者，多在三、五、七
月之间。下次之堕，必如期而然。正以先次伤此一经，再值此经，则遇阙不能过矣。况肾以系胞，而腰为肾之
府，故妊妇最忌腰痛，痛甚则坠，不可不防。○凡小产有远近，其在二、三月为近，五、六月为远。新受而产者
其势轻，怀久而产者其势重，此皆人之所知也。至若尤有近者，则随孕随产矣。盖胎元始肇，一月如珠露，二
月如桃花，三、四月而后血脉形体具，五、六月而后筋骨毛发生。方其初受，不过一滴之元津耳。此其橐 正
无根据，根 尚无地，巩之则固，决之则流。故凡受胎之后，极宜节欲，以防泛溢。盖明产者，胎已成形，小产
必觉；暗产者，胎仍似水，直溜何知？（张景岳）
论治
妇人妊娠，宜常服当归散主之。○妊娠养胎，白术散主之。○妇人有漏下者，有半产后因续下血都不绝者，
有妊娠下血者，胶艾汤主之。（《金匮》）
半产重于大产。盖大产如果熟自脱；小产如生采，破其皮壳，断其根蒂，岂不重于大产？但人轻忽者多。
治法宜补形气，生新去瘀。若未足月，痛而欲产者，补中汤安之；若产而血不止者，人参黄 汤止之；若胎气
弱而小产者，八珍汤固之。（薛立斋）
堕胎与半产有别。如一、二、三、四月，胎未成形而下者，名曰堕胎；五、六、七、八月，胎已成形而
下者，名曰半产。总属妊妇气血弱，冲任虚，以致胎元不固。《千金》保胎丸一方最
妙。赵养葵以六味地黄汤加杜仲、续断、五味子、阿胶，为安胎之圣药，亦传心之秘典也。○堕胎血出过多者，
经脉损而冲任之气虚不摄，是不足也，当大补气血，以固其脱。堕胎血凝作痛者，外邪乘而败浊之血闭而不流，
是有余也，当导瘀消蓄，以温其经。不特堕胎为然，即产后见是证，亦宜以此法治之。（萧慎斋）
叶孕三月，兢兢自持，至期必动。医家非凉血则固气，非升举则利气，百药不效，其胎必堕，皆由易于受
而易于堕也。究堕之之故，果安在哉？盖胎系于脾，而根于肾。其屡孕者，相火之有余也；屡堕者，相火之过
旺也；屡堕而不先不后者，脾土主有信也。缪氏谓三月阳明脉养胎，其人脾土素弱，而相火摇摇，风木侮之，
无故自落，岂寻常意见所能补救者耶？必也戒怒以舒肝，却虑以安脾，节欲以养肾，然后用先君子猪肚丸药，
清相火以实脾土，土旺则四脏之气皆旺，精自生而气自固，不必虑难安易落之胎矣。虽然，药宜早服于未孕之
先，莫迟服于已孕之后，所谓未雨绸缪，不治已病治未病也。（《会心录》）
古人用黄芩安胎，是因子气过热，故用苦寒以安之。脾为一身之津梁，主内外诸气，而胎息运化之机全赖
脾土，故用白术以助之。然惟形瘦血热，营行过疾，胎动不安者，乃为相宜。若形弱气衰，胎常下坠者，非人
参举之不安；形实气盛，胎常不运者，非香、砂耗之不安；血虚火旺，腹常急痛者，非归、芍养之不安；体肥
痰盛，呕逆眩晕者，非苓、半豁之不安。凡此皆治母气之偏胜也。若因风寒所伤而胎不安者，则香苏散、葱豉
汤，量所宜用；伏邪时气，尤宜急下。凡此，俱安胎要诀。下药中独芒硝不可犯。（张飞畴）
安胎、固胎、养胎，必当察其由来，分其胎之所损，在气在血，何者之虚？胎与母病，孰先孰后？方制君、
臣、佐、使，各适其宜。岂可守一定之方，执而不通耶！（《推求师意》）

[Discussion on Etiology]
When Yang energy is applied and Yin energy transforms, conception occurs. If Qi and Blood are deficient and damaged, failing to nourish the fetus, the fetus will naturally miscarry. This is like a branch withering causing fruit to fall, or a vine collapsing causing flowers to drop. Alternatively, labor and anger may stir up internal fire, which can also lead to abortion. Just as wind shakes a tree or a person breaks a branch. (From *Shen Shi Zun Sheng Shu*)
If miscarriages occur too frequently, Qi and Blood are severely depleted, and the fetus lacks nourishment, hence frequent miscarriages. It is like water drying up causing crops to wither, or soil eroding causing trees to fall. (Wang Shishan)
During pregnancy, if there is distension and bearing-down sensation in the lower abdomen, one must guard against the risk of spontaneous abortion (minor miscarriage). Once vaginal bleeding appears, stability is difficult to maintain. When branches wither, fruits fall; urgently tonify the Kidney. When frames rot, bells fall; urgently tonify the Spleen. (From *Jian Wen Lu*)
When donkeys or horses are pregnant, if a male approaches, the female kicks it with her hooves; this is called "protecting the fetus," so they rarely experience minor miscarriages. In humans, the fetus is suspended in the Uterus (Bao Gong), nourished by Qi and Blood. Stillness allows Spirit to be stored internally. If desire-fire moves, Spirit leaks out, fire disturbs the interior, and the fetus aborts. Can one not be cautious? (From *Chan Bao Bai Wen*)
To preserve the fetus, one should nourish the Spleen and Stomach. The Spleen and Stomach are the officials of granaries, from which Zang-Fu organs receive their endowment, and embryos are nourished thereby. The Stomach belongs to the Yangming channel, which is the head of the Chong and Ren vessels. (From *Xue Shi Yi An*)
Frequent abortions during pregnancy are invariably due to deficiency and damage of Qi and Blood. Causes of deficiency include: innate weak constitution, declining age and vitality, exhaustion of essence and vitality due to worry, anger, labor, and hardship, and damage to vital energy due to imprudent sexual activity. Additionally, falls, dietary issues, etc., can all injure Qi and Blood. If Qi and Blood are injured yet the fetus remains unharmed, this requires an intact congenital foundation; ordinary people do not have this. Moreover, throughout the ten months of gestation, different meridians govern nourishment each month. Thus, recurrent minor miscarriages often occur between the 3rd, 5th, and 7th months. Subsequent miscarriages tend to happen at the same time. This is because the previous injury affected a specific meridian, and when that meridian becomes active again, the defect prevents passage. Furthermore, the Kidney suspends the Uterus, and the waist is the mansion of the Kidney. Therefore, pregnant women most fear lower back pain; severe pain leads to bearing down, so prevention is essential. ○ Minor miscarriages vary in timing: those in the 2nd and 3rd months are considered "early" (near), while those in the 5th and 6th months are "late" (far). Abortion shortly after conception has a lighter course; abortion after long gestation has a heavier course, which is common knowledge. There are even earlier cases where abortion occurs immediately upon conception. Initially, fetal vitality begins: in the first month like dew, in the second like peach blossoms. By the 3rd-4th months, blood vessels and form are established; by the 5th-6th months, bones, sinews, hair, and teeth grow. At initial conception, it is merely a drop of primordial fluid. Its root has no basis, its foundation no ground; consolidation makes it firm, rupture makes it flow. Therefore, after conception, one must strictly abstain from sexual desire to prevent overflow. "Manifest abortion" implies the fetus has formed, and minor miscarriage is felt; "hidden abortion" implies the fetus is still like water, flowing away unnoticed. (Zhang Jingyue)
[Discussion on Treatment]
For pregnant women, Danggui San (Angelica Powder) should be taken regularly. ○ For nourishing the fetus during pregnancy, Baizhu San (Atractylodes Powder) is indicated. ○ For women with metrorrhagia (bleeding between periods), continuous bleeding after partial abortion, or bleeding during pregnancy, Jiao'ai Tang (Colla Corii Asini and Mugwort Decoction) is indicated. (From *Jin Gui Yao Lue*)
Partial abortion (minor miscarriage) is more severe than full-term delivery. Full-term delivery is like a ripe fruit falling naturally; partial abortion is like picking unripe fruit, breaking the shell and severing the root. Is it not more severe? Yet people often neglect it. Treatment should tonify Form and Qi, generate new tissue, and remove stasis. If preterm labor pains occur before term, Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) calms it; if bleeding continues after delivery, Renshen Huangqi Tang (Ginseng and Astragalus Decoction) stops it; if weak fetal Qi causes minor miscarriage, Bazhen Tang (Eight Treasures Decoction) secures it. (Xue Lizhai)
Abortion (early loss) differs from partial abortion (later loss). Loss in the 1st-4th months before formation is called abortion; loss in the 5th-8th months after formation is called partial abortion. Both belong to deficiency of Qi and Blood in the pregnant woman and deficiency of the Chong and Ren vessels, leading to insecure fetal vitality. The Baotai Wan (Fetus-Preserving Pill) from *Qianjin Fang* is excellent. Zhao Yangkui uses Liuwei Dihuang Tang (Six-Ingredient Rehmannia Decoction) plus Duzhong, Xuduan, Wuweizi, and Ejiao as a sacred medicine for calming the fetus, a secret transmission. ○ For excessive bleeding after abortion, meridians are damaged and Qi of Chong/Ren is deficient and failing to control, representing Deficiency; urgently tonify Qi and Blood to secure collapse. For blood coagulation causing pain after abortion, external pathogens invade, turbid blood blocks and stagnates, representing Excess; guide out stasis, eliminate accumulation, and warm the meridians. This applies not only to abortion but also to postpartum presentations of these syndromes. (Xiao Shenzhai)
Patient Ye maintained strict caution during the first three months of pregnancy, but movement inevitably occurred at term. Physicians used either cooling-blood or Qi-stabilizing methods, or lifting or Qi-promoting methods, but hundred medicines failed, and the fetus aborted. This is due to being easy to conceive but easy to lose. Investigating the cause: the fetus is tied to the Spleen and rooted in the Kidney. Frequent pregnancies indicate excess of Ministerial Fire; frequent abortions indicate excessive Ministerial Fire; abortions occurring precisely on schedule indicate the Spleen Earth's reliability. Miu Xi Yong stated that in the 3rd month, the Yangming channel nourishes the fetus. If the patient has inherently weak Spleen Earth and shaking Ministerial Fire, Wind Wood attacks it, causing spontaneous loss without cause. How can ordinary opinions remedy this? One must avoid anger to soothe the Liver, eliminate worry to calm the Spleen, and restrain desire to nourish the Kidney. Then use the Pig Stomach Pill (Zhudu Wan) to clear Ministerial Fire and solidify Spleen Earth. When Earth is strong, Qi of the Four Zang organs strengthens, Essence generates, and Qi secures, eliminating worries about unstable fetuses. Although, medicine should be taken early before pregnancy, not late after conception—this is preparing for rain before it falls, treating disease before it arises. (From *Hui Xin Lu*)
Ancients used Huangqin (Scutellariae Radix) to calm the fetus because fetal Qi was too hot, using bitter-cold to calm it. The Spleen is the pivot of fluids in the body, governing internal and external Qi, and fetal respiration and transformation rely entirely on Spleen Earth, so Baizhu (Atractodis Rhizoma) is used to assist. However, this is suitable only for thin individuals with Heat in Blood, rapid Ying circulation, and restless fetus. For weak form and衰竭 Qi with frequent bearing down, Renshen (Ginseng Radix) is needed to lift; for robust form and abundant Qi with stagnant fetus, Xiangfu and Sharen are needed to move Qi; for Blood deficiency with Fire hyperactivity and abdominal cramping, Danggui and Shaoyao are needed to nourish; for obesity with Phlegm abundance, vomiting, and dizziness, Fuling and Banxia are needed to resolve Phlegm. These all treat maternal Qi imbalance. If fetal unrest is caused by Wind-Cold, Xiangsu San or Congchi Tang should be used appropriately; for latent pathogens or seasonal epidemics, purgatives are urgent. These are key principles of calming the fetus. Among purgatives, Mangxiao (Natrii Sulfas) must never be used. (Zhang Feichou)
Calming, securing, and nourishing the fetus requires investigating the origin, distinguishing the damage to the fetus, whether in Qi or Blood, and which aspect is deficient. Is it fetal disease or maternal disease, which came first? Then formulate Jun, Chen, Zuo, Shi roles appropriately. How can one stick rigidly to a fixed formula? (From *Tui Qiu Shi Yi*)
[Pulse Diagnosis]
The Cun Kou pulse is Wiry (Xian) and Large (Da). Wiry indicates reduction/deficiency; Large indicates Hollow (Kou). Reduction indicates Cold; Hollow indicates Deficiency. Deficiency and Cold clashing is named Ge (Leather) pulse. In women, this indicates partial abortion and metrorrhagia. (Zhang Zhongjing)
